IMPROVEMENT IN HARVESTEARS.

Specification forming part of Letters Patent No. 27,010, dated January31, 1860.

To all whom it may concern:

Be it known that I, J. SCOVILLE, of Buffalo, in the county of Erie andState of New York, have invented a new and Improved Grain and GrassHarvester; and I do hereby declare that the following is a full, clear,and exact description of the same, reference being had to the annexeddrawings, making a part of this specitication, in which- Figure l is aside view of my invention. Fig. 2 is a vertical section of the saine,taken in the line x fr, Fig. l. Fig. 3 is a plan or top view of thesame.

Similar letters of reference indicate correspondin g parts in theseveral figures.

To enable those skilled in the art to fully understand and construct myinvention, I will proceed to describe it.

A represents the main frame of the machine, which may be of' triangularor an approximate form, a draft-pole, B, being attached to its front endand the cuitingdevice (not represented) attaehed to its back end. Themain frameAis provided with a longitudinal bar, a., between which andthe side bar, b, of' the framethe supportingr and driving wheel C isplaced. The axis c of the wheel O has its end fitted in slottedjournal-boxes D D, attached one to the bar a and the other to the bar bof the main frame, the curvature of the slots corresponding to the curvethe main frame would describe in rising and falling in order to keep thepinion d of the sickle-driving mechanism in gear with the toothed rim eon the driving-wheel; or, in other words, the curved slot-s are struckfrom the axis ofthe pinion d. Thiswill be clearly understood byreferring to Fig. 1. This is the only attachment existing between themain frame and the driving and supporting wheel. The sickle, which maybe of the ordinary reciprocating kind, is driven from the wheel O l bythe gearing d e, already alluded to, in connection with gearing f g andcrank-pulley h. This constitutes a driving mechanism common tp manyharvesting-machines.

To the frontend ofthe main frame A an upright, D', is attached, and tothe upper end of the upright D an elastic lever-seat bar, E, is securedby a joint, t'. The elastic lever-seat bar E has pcndantsjj attached toit at about its center, and the lower ends of these pendants are fittedin the axis c of wheel O. the axis being allowed to turn freely in thependants. On the back end of lever-seat bar E the drivers seat F isplaced. p

From the above description it will be seen that the main frame A mayrise and fall independently of the wheel C, in consequence of its axis cbeing placed loosely in the slotted journal-boxes I), and it will alsobe seen that the weight of the driver on the seat F is trans miited bythe pendantsjj to the axis c ot' the wheel C, as also is a portion ofthe weight et' the frame A. The wheel C therefore will be' preventedfrom slipping as the machine is drawn along, and the wheel and mainframe, while being connected together, still allowed an independentmovement, so that the sickle may conlorm to the inequalities of theground without being at all affected by the movement of the wheel inpassing over undulating surfaces. p

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. The combination of the'hinged lever-seat bar E with the slottedjournal-boxes D and axis c, as and for the purpose herein shown anddescribed.

2. The employment of the slotted journalboxes D, in combination with thetractionwheel O and pinion d, as herein shown and described, wherebysaid traction-wlieel is left free to rise-and fall independently of theframe A, for the purposes set forth.
